As temperatures rise, so do cooling costs. At Mechanical Air Conditioning, we know that keeping your home comfortable without breaking the bank is a top priority. One of the simplest and most effective ways to manage your energy usage is by optimizing your thermostat settings. Whether you have a traditional programmable thermostat or a cutting-edge smart model, small adjustments can lead to significant savings. Here are the best thermostat strategies to lower your cooling costs while maintaining comfort with your air conditioning.

Set Your Thermostat to the Right Temperature
The Department of Energy recommends setting your thermostat to 78°F when you’re home and raising it when you’re away. This setting balances energy efficiency and comfort, helping you reduce unnecessary energy consumption. Every degree you raise the temperature can result in savings of about 3% on your cooling bill.
For the best efficiency:
- When you’re at home and awake, keep the thermostat at 78°F.
- When you’re away, raise the temperature by 7–10 degrees.
- At night, you can keep it slightly higher if comfortable, or use ceiling fans to maintain airflow.
Use a Programmable or Smart Thermostat
If you’re still manually adjusting your thermostat, you’re likely missing out on major energy savings. Programmable thermostats allow you to set cooling schedules that adjust automatically based on your daily routine. Smart thermostats take this a step further by learning your habits and optimizing energy use accordingly.
Smart thermostats can:
- Learn your schedule and automatically adjust temperatures.
- Detect when no one is home and adjust settings to save energy.
- Provide remote access, allowing you to control temperatures from your phone.
- Analyze energy usage, helping you identify areas to save even more.
Use Ceiling Fans to Your Advantage
A ceiling fan doesn’t actually lower the temperature, but it makes you feel cooler by improving air circulation. This allows you to keep the thermostat set higher while maintaining the same level of comfort. In the summer, make sure your fans are rotating counterclockwise to push cool air downward.
Take Advantage of Natural Cooling
Reduce reliance on your AC system by maximizing natural cooling methods:
- Close blinds or curtains during the day to block out heat from the sun.
- Open windows and use cross-ventilation in the evening when outdoor temperatures drop.
- Install blackout shades or reflective window films to minimize heat gain.
Upgrade to a Wi-Fi Smart Thermostat
If you’re using an outdated thermostat, upgrading to a Wi-Fi-enabled smart thermostat is one of the best investments you can make in energy efficiency. Modern smart thermostats from brands like Nest, Ecobee, and Honeywell provide advanced control over your cooling system, ensuring optimal performance and energy savings. With real-time temperature monitoring, remote access, and AI-driven learning capabilities, these thermostats make energy savings effortless.
